An architect make a model of a new house. The model shows a title patio in the backyard. In the model, each tile has length 2/3 inches. And with 1/4in. The actual tiles have length 1/2 feet in width 3/16 feet. What is the ratio of the length of tile in the model to the area of an actual tile?

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.21. what can you conclude? 2(0.21) = 0.42 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time, so the test is not statistically significant. 0.21 > 0.05; the test is statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time, so the test is not statistically significant. p = 1 - 0.21 = 0.79 > 0.05; the test is statistically significant.
